Ion-selective electrode (ISE) (indirect potentiometry). The ISE module of the P-Module performs indirect measurement of electromotive for (EMF). The ISE module measures the EMF difference between an ISE and a reference electrode. The EMF of the ISE is dependent on the ion concentration of the sample. The EMF of the reference electrode is constant. The P-Module uses an electronic calculation circuit to convert the EMF of the sample to the ion concentration of the sample.(Package insert: Boehringer Mannheim ISE reagent; Indianapolis, IN 46256, 1997)
